I have found a significant amount of water any time I open the drain after sailings. Only one hull is affected: the other is so tight that actually releases gas when I open the drain. In order to understand from where the hull takes water, i filled the hull with water so to spot leakages. Water only has come out from the hole that is almost on top of the hull I guess for security reason.

Any hint ?

Thanks

Thank youI have also learned that even the other hull may have problem since when I open the drain plug hear a puff of air. So http://www.hobiecat.com/articles/hull-l ... ection,88/ says that it means the hull is not breathing causing longterm structural problem. It does not say though what can I do to correct it. Any hint ?

Thank you again

Instead of drilling "breather" holes in the hulls I recommend simply unscrewing the ports at the bottom of the storage compartments during hot weather. I close them when I go sailing and open them afterward. Keeps pressure from building up in hot weather without having to drill holes.
